A Biometric expert, or an expert in biometric recognition context, refers to a method that expresses an opinion on the likelihood of an identity by analyzing a signal that it is specialized on, e.g. a fingerprint expert using minutiae, a lip-motion expert using statistics of optical-flow. Accordingly, there can be several experts associated with the same sensor data, each analyzing the data in ...

In this paper, a general approach is proposed to address a full Bayesian analysis for the class of quadratic natural exponential families in the presence of several expert sources of prior information. By expressing the opinion of each expert as a conjugate prior distribution, a mixture model is used by the decision maker to arrive at a consensus of the sources. A hyperprior distribution on the...

This paper reports on the automatic metadata generation applications (AMeGA) project’s metadata expert survey. Automatic metadata generation research is reviewed and the study’s methods, key findings and conclusions are presented. Participants anticipate greater accuracy with automatic techniques for technical metadata (e.g., ID, language, and format metadata) compared to metadata requiring int...

This paper aggregates experts’ opinion on the climate sensitivity parameter fromMorgan and Keith [1995] using the Transferable Belief Model. The non-independence of experts issue is dealt with by organizing experts into schools of thought, requiring non-interactivity only across but not within groups. The issue of dissonance, that is wide qualitative differences in beliefs, is dealt with by usi...

Subject of our work is to explore and analyze the referred relationships between the emerging ICT landscape in the European societal and economic context, and the development and provision of e-Accessibility, within a perspective of 10 years. Some core areas of concern we deal with are represented by the following questions: Which are the trends that may affect the future of e-Accessibility (in...

OBJECTIVE This survey of published researchers of long-acting reversible contraceptives (LARCs) examines their opinions about important barriers to LARC use in the United States (US), projections for LARC use in the absence of barriers and attitudes toward incentives for clinicians to provide and women to use LARC methods. STUDY DESIGN We identified 182 authors of 59 peer-reviewed papers on L...

AIM This study aims at examining the difficulty in performing forced eruption of impacted maxillary canines, using CBCT information and according to experienced orthodontist's opinion. The second aim was to find the most important factors related to this decision. METHODS Based on a careful literature review on impacted maxillary canines, ten main factors were selected to assess difficulties ...

Accompanying the increasing availability of parallel computing technology is a corresponding growth of research into the development, implementation, and testing of parallel algorithms. This paper examines issues involved in reporting on the empirical testing of parallel mathematical programming algorithms, both optimizing and heuristic. We examine the appropriateness of various performance met...
